Really should have opted for the proper short barrel to go with the M4 configuration on the AR. Especially for personal defense in the house. The minor accuracy difference is much less of an issue than barrel flagging or the risk of not having enough distance to bring it up. Although realistically, flagging yourself shouldn't be an issue in the average break-in scenario. Must say though, that IS one of the only scenarios I like the junky 5.56 for.
